Abstract
The utility model discloses a circular knitting machine spindle bearing, which comprises an outer ring (1), an inner ring (2) and a rolling body (3) arranged between the inner ring (2) and ball tracks (5) arranged on the outer ring (1). Retainers (4) are arranged on two sides of the rolling body (3), the inner ring (2) includes two symmetrical parts, each part is provided with a semi-circular ball track (6), the outer ring (1) is provided with two ball tracks (5), and the semi-circular ball tracks (6) are correspondingly matched with the ball tracks (5) arranged on the outer ring (1) so that the rolling body (3) can roll. The structure of the circular knitting machine spindle bearing enhances axial bearing capacity of a bearing effectively, and can bear a certain amount of overturning moment, thereby prolonging service life of the bearing.
Description
Technical field
The utility model relates to the circular knitting machine main shaft bearing that uses in a kind of Textile Machinery, belongs to technical field of rolling bearings.
Background technique
Deep groove ball bearing on the existing Textile Machinery, its structure as shown in Figure 1, it comprises that outer ring 1, inner ring 2, rolling element 3, retainer 4 form.Be respectively equipped with the raceway 5 that rolls for rolling element 3 on the inner headed face of the periphery of described inner ring 2 and outer ring 1, the raceway radius is slightly larger than the rolling element radius.
There is following defective in actual use in this bearing: at first: it mainly bears radial load and a certain amount of thrust load, when thrust load moment becomes big, the life-span of bearing will be had a strong impact on, thereby affect indirectly the life-span of frame, secondly, Bearing Installation is the setting mode, beat and have relatively high expectations, just need bearing can bear a certain amount of tilting moment this moment, and like this, general deep groove ball bearing is with regard to improper this occasion.
The model utility content
Technical problem to be solved in the utility model provides a kind ofly can bear bigger radial and axial load, and can bear the bearing of a certain amount of tilting moment.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: a kind of circular knitting machine main shaft bearing, comprise the rolling element that is provided with between outer ring, inner ring and inner ring, the outer ring raceway, the rolling element both sides also are provided with retainer, described inner ring is the two halves of symmetry, be respectively arranged with the half-turn raceway on per half, described outer ring is provided with two raceways, and described half-turn raceway cooperates for the rolling element rolling with raceway on the outer ring accordingly.
In order to reduce rolling friction, the radius of described raceway and half-turn raceway is greater than the radius of rolling element.
The utility model bearing is because be two raceways, and has bigger wrapping angle, similar to two single-row contact ball bearings of arranging back-to-back in design, so have rigidity preferably, and can bear bigger axial and radial load and a certain amount of tilting moment, this bearing is a separable type in addition, and is more convenient during assembling.
The utility model bearing has effectively strengthened the axial carrying capacity of bearing, and can bear a certain amount of tilting moment, thereby has prolonged the working life of bearing.

Fig. 2 is the structural representation of the utility model bearing.
Embodiment
As shown in Figure 2, a kind of circular knitting machine main shaft bearing, comprise the rolling element 3 that is provided with between outer ring 1, inner ring 2 and inner ring 2, outer ring 1 raceway 5, rolling element 3 both sides also are provided with retainer 4, described inner ring 2 is the two halves of symmetry, be respectively arranged with half-turn raceway 6 on per half, described outer ring 1 is provided with two raceways 5, and described half-turn raceway 6 cooperates for rolling element 3 rollings with raceway 5 on the outer ring accordingly.
The radius of described raceway 5 and half-turn raceway 6 is in order to reduce rolling friction, to improve the life-span of rolling element 3 greater than the radius of rolling element 3.
The utility model is because two raceways of design, and has bigger wrapping angle, similar to two single-row contact ball bearings of arranging back-to-back, so have rigidity preferably, and can bear bigger axial and radial load and a certain amount of tilting moment, this bearing is a separable type in addition, and is more convenient during assembling.
The foregoing description limits the utility model never in any form, and every employing is equal to replaces or technological scheme that the mode of equivalent transformation obtains all drops in the protection domain of the present utility model.
Claims (2)
1. circular knitting machine main shaft bearing, comprise the rolling element (3) that is provided with between outer ring (1), inner ring (2) and inner ring (2), outer ring (1) raceway (5), rolling element (3) both sides also are provided with retainer (4), it is characterized in that: described inner ring (2) is the two halves of symmetry, be respectively arranged with half-turn raceway (6) on per half, described outer ring (1) is provided with two raceways (5), and described half-turn raceway (6) cooperates for rolling element (3) with raceway (5) on outer ring (2) accordingly and rolls.
2. circular knitting machine main shaft bearing according to claim 1 is characterized in that: the radius of described raceway (5) and half-turn raceway (6) is greater than the radius of rolling element (3).
